Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719824, here are decompositions:

5 + 8719819 = 8719824
7 + 8719817 = 8719824
11 + 8719813 = 8719824
23 + 8719801 = 8719824
53 + 8719771 = 8719824
163 + 8719661 = 8719824
233 + 8719591 = 8719824
251 + 8719573 = 8719824

Showing the first eight; more decompositions exist.
